Metadata structure
To get access to data about token You need to follow these steps:
- In BNB Smart Chain Explorer find MetaproMetaAsset Contract
0xa293D68684Be29540838Dc8A0222De0c43c6b5B4 - Click on Contract and Read Contract
View of contract on BSC Scan - In this tab we have all methods which we can read from MetaproMetaAsset Contract
- Last method calls "uri" which get data about token.
Method called "uri" where you can insert TokenId - Copy link from response and paste it on new browser tab
Example of JSON response with all data about token
⚠️ Hint : If you want to have parsed data like on picture above it needs JSON formatter extension installed on browser
- Metadata response
